Tsetse flies

In the reserve, we spotted these black and blue flags and asked the ranger what they were for.

“They are tsetse fly traps” He replied. “The flies are attracted to the bright blue cloth. When they land, they are killed by the insecticide on the fabric.”

Later, while pedaling through a remote stretch of Tanzania, Paul suddenly felt flies biting him. He quickly changed to a light colored shirt and we sprayed the black backs of our panniers with DEET. It worked like magic!
